Slight v-shape with good tech and detail, treble can be too much but has that sizzle and sparkliness some people will like.

Endgame Harman, one of the smoothest IEMs I've heard with Tangzu Sancai tips (regular). Some units might be hotter in the treble/pzt timbre

A slightly more V-shaped version of the Truthear Nova. A bit more bass, a bit more treble. Not as vocal focused. Some of the best technical performance at $150. Good accessories. Shells are more compact than the Nova.

The Simgot Supermix 4 packs a quadbrid driver configuration (1DD+1BA+1 Planar+1 PZT) into a comfortable resin shell. Its sound follows a U-shaped signature aligned with the Harman IE 2019 target, emphasizing sub-bass rumble and crisp upper-midrange clarity while keeping lower mids slightly recessed. The bass is deep and textured, though mid-bass punch can feel soft, and vocals sometimes edge into shoutiness at higher volumes.

Treble delivery is a standout, with the planar and PZT drivers offering snappy articulation and air without harsh sibilance. Technical performance is strong for the price, featuring a wide soundstage and precise imaging that excels in gaming scenarios. However, low impedance makes it source-sensitive, and accessories feel minimal with only one set of tips included.

While not class-leading in resolution, the Supermix 4 delivers cohesive tonality across its diverse drivers, making it a versatile choice for bass-forward genres and competitive gaming. Its slight warmth and holographic staging compensate for minor midrange thinning, offering solid value despite fierce competition.
